/**
 * \file cpl_string.h
 *
 * Various convenience functions for working with strings and string lists. 
 *
 * A StringList is just an array of strings with the last pointer being
 * NULL.  An empty StringList may be either a NULL pointer, or a pointer to
 * a pointer memory location with a NULL value.
 *
 * A common convention for StringLists is to use them to store name/value
 * lists.  In this case the contents are treated like a dictionary of
 * name/value pairs.  The actual data is formatted with each string having
 * the format "<name>:<value>" (though "=" is also an acceptable separator). 
 * A number of the functions in the file operate on name/value style
 * string lists (such as CSLSetNameValue(), and CSLFetchNameValue()).
