/**
* URI template aware utility class for building URIs from their components. See
* {@link javax.ws.rs.Path#value} for an explanation of URI templates.
*
* Builder methods perform contextual encoding of characters not permitted in
* the corresponding URI component following the rules of the
* application/x-www-form-urlencoded
* media type for query parameters and
* RFC 3986 for all other
* components. Note that only characters not permitted in a particular component
* are subject to encoding so, e.g., a path supplied to one of the {@code path}
* methods may contain matrix parameters or multiple path segments since the
* separators are legal characters and will not be encoded. Percent encoded
* values are also recognized where allowed and will not be double encoded.
*
* URI templates are allowed in most components of a URI but their value is
* restricted to a particular component. E.g.
*
UriBuilder.fromPath("{arg1}").build("foo#bar");
* would result in encoding of the '#' such that the resulting URI is
* "foo%23bar". To create a URI "foo#bar" use
* UriBuilder.fromPath("{arg1}").fragment("{arg2}").build("foo", "bar")
* instead. URI template names and delimiters are never encoded but their
* values are encoded when a URI is built.
* Template parameter regular expressions are ignored when building a URI, i.e.
* no validation is performed.
