/*DESCRIPTION:  
            the program reads CSV file and ask the user to choose between three quries :
                - Action query : return muscle responsible for an action.. user can just enter a part of words like" compr abd" instead of
                  "compresses abdomen". If action is not found,it cout that and asks if you need to try again.
                - Strengthen query: returns muscle(s) you need to work on
                - Diagnostic query: returns possible area pain related to  a muscle .
                + After you done, you will be offered to try another search */
/* METHODOLOGY: 
                This program will get information from a CSV "comma seperated values" file 
and  will assign it to typedefined vector<vector<string>> as a 2D vector of vectors represnting a table with cells each cell 
represented by Vector[raw][column] and contains only one string- this done by a global function that reads the stream and populates the 2D vec-.
#A class " Queriers" contains strings for names,actions,types,origins and locations and four public functions and a constructor.
Assigning data to variables in the class will be done through three functions representing the three possible queries
and they will be passed the variable througth an assigning function that is called by the constructor  
//constructor creats an object, calls the assigning function which then calls the proper function to assign values to variables 
in the class of that object.//
#Searching is done across one column and multiple raws.In query "Action", I have used (find-found) technique two times to search 
for both words (strings)in one cell. To find just a part of a string,I've used {string.find(substr)} method. 
ie; if user enter " comp abd " it will return true for "compresses abdomen"
