+function filenames = dirKPM(dirname, ext, varargin)
+% dirKPM Like the built-in dir command, but returns filenames as a cell array instead of a struct
+%
+% filenames = dirKPM(dirname)
+% returns all files, except '.' and '..'
+%
+% filenames = dirKPM('images', '*.jpg')
+% returns files with this extension
+%   eg filenames{1} = 'foo.jpg' etc
+%
+% OPTIONAL ARGUMENTS [default in brackets]
+% filenames = dirKPM('images', '', param1, val1, param2, val2, ...)
+%
+% 'fileType'='image' ['all'] means return files with extension .jpg, .png, .bmp
+%
+% 'prepend'=1 [0] means preprend folder name to filename
+%    eg filenames{1} = 'images/foo.jpg'
+%
+% 'doSort'=1 [1] means sort filenames in ascending alphanumerical order (where possible)
+%
+% 'doRecurse'=1 [0] recursive dir, apply the same dirKPM call on all
+% subfolders (decrease MAXDEPTH option to prevent recursion from branching
+% too explosively)
