/**
 * An implementation of {@link HttpPartParser} that takes in the strings and tries to convert them to POJOs using constructors and static create methods.
 *
 * <p>
 * The class being created must be one of the following in order to convert it from a string:
 *
 * <ul>
 * 	<li>
 * 		An <jk>enum</jk>.
 * 	<li>
 * 		Have a public constructor with a single <c>String</c> parameter.
 * 	<li>
 * 		Have one of the following public static methods that takes in a single <c>String</c> parameter:
 * 		<ul>
 * 			<li><c>fromString</c>
 * 			<li><c>fromValue</c>
 * 			<li><c>valueOf</c>
 * 			<li><c>parse</c>
 * 			<li><c>parseString</c>
 * 			<li><c>forName</c>
 * 			<li><c>forString</c>
