// PROBLEM STATEMENT
// You have received the transcript of an online chat.  Each element of transcript corresponds to a line.  You want to know how many times name said something.  To do this, count how many lines begin with name immediately followed by a colon.  This comparison is case sensitive.
// 
// DEFINITION
// Class:ChatTranscript
// Method:howMany
// Parameters:vector <string>, string
// Returns:int
// Method signature:int howMany(vector <string> transcript, string name)
// 
// 
// CONSTRAINTS
// -transcript will contain between 1 and 50 elements inclusive.
// -Each element of transcript will contain between 1 and 50 characters inclusive.
// -Each character in each element of transcript will have ASCII value between 32 and 126 inclusive.
// -name will contain between 1 and 50 characters inclusive.
// -Each character in name will be a letter (A-Z, a-z) or a digit (0-9).
// 
// 
// EXAMPLES
// 
// 0)
// {
// "Bob: Hello Tim.",
// "Tim: Hello Bob.",
// "Bob: How are ya Tim?",
// "Frank: Stop chatting!"
// }
// "Bob"
// 
// Returns: 2
// 
// Bob managed to say two things before Frank entered the conversation.
// 
// 1)
// {
// "Bob: This is a long",
// "sentence that takes 2 lines.",
// "Tim: Yes it is.",
// "Bob : I am not Bob.",
// "Frank: No you aren't!",
// " Bob: Neither am I."
// }
// "Bob"
// 
// Returns: 1
// 
// Only one line begins with "Bob:" (quotes for clarity).
// 
// 2)
// {
// "Crazy1010: !@LK%#L%K @#L%K @#L%K@#L%K2kl53k2",
// "Bob: You are crazy.",
// "Crazy1010 Yup #@LK%$L!K%LK%!K% !K afmas,"
// }
// "Crazy1010"
// 
// Returns: 1
// 
// 3)
// {
// "A:A:A:A:A:A:A:A:A",
// "b:b:b:b:b:b:b:b:b"
// }
// "B"
// 
// Returns: 0
// 
// 4)
// {"A:A:A:A:A:A:A:A:A"}
// "A"
// 
// Returns: 1
//
