+	// summary:
+	//		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.
