This helper class can be used to solve the localization problems, usually related to the textual files reading/writing, namely when floating point values are read / written with API functions. The problem relates to such locale specific settings as decimal point separator, thousands separator, etc.
To use the Localizer class, just create a local variable in the beginning of the code where you need to read / write data from textual file(s). The constructor of the class forces setting "C" locale temporariy. The destructor switches back to the initial locale.
