142% INI = ini2struct(FileName)
143%
144% This function parses INI file FileName and returns it as a structure with
145% section names and keys as fields.
146%
147% Sections from INI file are returned as fields of INI structure.
148% Each fiels (section of INI file) in turn is structure.
149% It's fields are variables from the corresponding section of the INI file.
150%
151% If INI file contains "oprhan" variables at the beginning, they will be
152% added as fields to INI structure.
153%
154% Lines starting with ';' and '#' are ignored (comments).
155%
156% See example below for more information.
157%
158% Usually, INI files allow to put spaces and numbers in section names
159% without restrictions as long as section name is between '[' and ']'.
160% It makes people crazy to convert them to valid Matlab variables.
161% For this purpose Matlab provides GENVARNAME function, which does
162%  "Construct a valid MATLAB variable name from a given candidate".
163% See 'help genvarname' for more information.
164%
165% The INI2STRUCT function uses the GENVARNAME to convert strange INI
166% file string into valid Matlab field names.
