* \brief Ini file reader module.
*
* The format accepted is:
* - Sections must begin at beginning of line. [ Long name ] will be found only if " Long name " is specified as section name.
* - key can contain any spaces at the beginning and before '=' but not in the middle. Eg. "long key name" is not valid.
* - values will be stripped of spaces at the beginning and will run until end-of-line. Eg. "= long value" will be treated as "long value".
* - no nested sections are allowed.
* - no comments are allowed inside a line with key=value pair.
* - every line that doesn't contain a '=' or doesn't start with '[' will be ignored.
