-" Airline themes are generated based on the following concepts:
-"   * The section of the status line, valid Airline statusline sections are:
-"       * airline_a (left most section)
-"       * airline_b (section just to the right of airline_a)
-"       * airline_c (section just to the right of airline_b)
-"       * airline_x (first section of the right most sections)
-"       * airline_y (section just to the right of airline_x)
-"       * airline_z (right most section)
-"   * The mode of the buffer, as reported by the :mode() function.  Airline 
-"     converts the values reported by mode() to the following:
-"       * normal
-"       * insert
-"       * replace
-"       * visual
-"       * inactive
-"       The last one is actually no real mode as returned by mode(), but used by
-"       airline to style inactive statuslines (e.g. windows, where the cursor
-"       currently does not reside in).
-"   * In addition to each section and mode specified above, airline themes 
-"     can also specify overrides.  Overrides can be provided for the following
-"     scenarios:
-"       * 'modified'
-"       * 'paste'
-"
-" Airline themes are specified as a global viml dictionary using the above
-" sections, modes and overrides as keys to the dictionary.  The name of the
-" dictionary is significant and should be specified as:
-"   * g:airline#themes#<theme_name>#palette
-" where <theme_name> is substituted for the name of the theme.vim file where the
-" theme definition resides.  Airline themes should reside somewhere on the
-" 'runtimepath' where it will be loaded at vim startup, for example:  
-"   * autoload/airline/themes/theme_name.vim
-"
-" For this, the dark.vim, theme, this is defined as
-let g:airline#themes#dark#palette = {}
-
-" Keys in the dictionary are composed of the mode, and if specified the
-" override.  For example:
-"   * g:airline#themes#dark#palette.normal 
-"       * the colors for a statusline while in normal mode
-"   * g:airline#themes#dark#palette.normal_modified 
-"       * the colors for a statusline while in normal mode when the buffer has
-"         been modified
-"   * g:airline#themes#dark#palette.visual 
-"       * the colors for a statusline while in visual mode
-"
-" Values for each dictionary key is an array of color values that should be
-" familiar for colorscheme designers:
-"   * [guifg, guibg, ctermfg, ctermbg, opts]
-" See "help attr-list" for valid values for the "opt" value.
-"
-" Each theme must provide an array of such values for each airline section of
-" the statusline (airline_a through airline_z).  A convenience function, 
-" airline#themes#generate_color_map() exists to mirror airline_a/b/c to
-" airline_x/y/z, respectively.
-
-" The dark.vim theme:
-let s:airline_a_normal   = [ '#00005f' , '#dfff00' , 17  , 190 ]
-let s:airline_b_normal   = [ '#ffffff' , '#444444' , 255 , 238 ]
-let s:airline_c_normal   = [ '#9cffd3' , '#202020' , 85  , 234 ]
-let g:airline#themes#dark#palette.normal = airline#themes#generate_color_map(s:airline_a_normal, s:airline_b_normal, s:airline_c_normal)
-
-" It should be noted the above is equivalent to:
-" let g:airline#themes#dark#palette.normal = airline#themes#generate_color_map(
-"    \  [ '#00005f' , '#dfff00' , 17  , 190 ],  " section airline_a
-"    \  [ '#ffffff' , '#444444' , 255 , 238 ],  " section airline_b
-"    \  [ '#9cffd3' , '#202020' , 85  , 234 ]   " section airline_c
-"    \)
-"
-" In turn, that is equivalent to:
-" let g:airline#themes#dark#palette.normal = {
-"    \  'airline_a': [ '#00005f' , '#dfff00' , 17  , 190 ],  "section airline_a
-"    \  'airline_b': [ '#ffffff' , '#444444' , 255 , 238 ],  "section airline_b
-"    \  'airline_c': [ '#9cffd3' , '#202020' , 85  , 234 ],  "section airline_c
-"    \  'airline_x': [ '#9cffd3' , '#202020' , 85  , 234 ],  "section airline_x

-"    \  'airline_z': [ '#00005f' , '#dfff00' , 17  , 190 ]   "section airline_z
-"    \}
-"
-" airline#themes#generate_color_map() also uses the values provided as

-"   airline_b_to_airline_c
