+	//		Helper function to convert a simple pattern to a regular expression for matching.
+	//	description:
+	//		Returns a regular expression object that conforms to the defined conversion rules.
+	//		For example:  
+	//			ca*   -> /^ca.*$/
+	//			*ca*  -> /^.*ca.*$/
+	//			*c\*a*  -> /^.*c\*a.*$/
+	//			*c\*a?*  -> /^.*c\*a..*$/
+	//			and so on.
+	//
+	//	pattern: string
+	//		A simple matching pattern to convert that follows basic rules:
+	//			* Means match anything, so ca* means match anything starting with ca
+	//			? Means match single character.  So, b?b will match to bob and bab, and so on.
+	//      	\ is an escape character.  So for example, \* means do not treat * as a match, but literal character *.
+	//				To use a \ as a character in the string, it must be escaped.  So in the pattern it should be 
+	//				represented by \\ to be treated as an ordinary \ character instead of an escape.
+	//
+	//	ignoreCase:
+	//		An optional flag to indicate if the pattern matching should be treated as case-sensitive or not when comparing
+	//		By default, it is assumed case sensitive.
