		//		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.
		// tags:
		//		private
