使用说明:
在使用该配置库的时候,
1.请注意不要出现相同的配置项,否则会出现一些解析错误。
2.sec书写时请确保[]’在同一行出现。
3.sec名前除了空格符合法外其它的一切字符都将会导至该sec及其子项不可识别。
4.确保key与其的值在同一行否则会出现该key不被识别的异常。
5.在属性值中以双引号作起始并括起的值可以正确的被解析,但双引号后面的字符
将被忽略,引号本身也不作为字符串的一部分。若不以双引号作起始符,则整个字符串
将被正确的解析,包括引号本身也将作为字符串的一部分。为了避免异常,请不要使用
双引号,如果一定要使用,请以单引号或中文双引号代替。
6.请不要使用诸如'\r','\n','[',']',';''"',等特殊字符,以免这些特殊的字符组合
出现不可预见的异常。
7.在属性值中不要出现';',因为';'是以注释符存在的,';'后的所有字符都将
被认为是注释,如果一定要使用,请以中文''代替。
8. 在编写注释的时候注意不要把英文';'与中文的''相混,以免把注释当作正文,
把正文当作注释。

@brief Get number of sections in a dictionary
@param d Dictionary to examine
@return int Number of sections found in dictionary
This function returns the number of sections found in a dictionary.
The test to recognize sections is done on the string stored in the
dictionary: a section name is given as "section" whereas a key is
stored as "section:key", thus the test looks for entries that do not
contain a colon.
This clearly fails in the case a section name contains a colon, but
this should simply be avoided.
This function returns -1 in case of error.
