docs: Parses the template and appends the parsed components
  to the builder. The following
  code:
  <pre>
  import static com.damnhandy.uri.template.UriTemplateBuilder.var;
  
  ...
  
  UriTemplate template =
  UriTemplate.buildFromTemplate("http://example.com/")
  .template("foo/{id}{?filter}")
  .build();
  </pre>
  Will generate the following URI Template string:
  <pre>
  http://example.com/foo/{id}{?filter}
  </pre>
  
  @param template the uri template
  @return the UriTemplateBuilder
