Errors with insufficient information about code position. #66

Hi, guys.

Some places in the parser throw exceptions which do not provide information about code position. For example:

java.lang.ClassCastException: org.yaml.snakeyaml.nodes.ScalarNode cannot be cast to org.yaml.snakeyaml.nodes.MappingNode
at org.raml.parser.visitor.TemplateResolver.loopTemplateSequence(TemplateResolver.java:145)
at org.raml.parser.visitor.TemplateResolver.init(TemplateResolver.java:129)
at org.raml.parser.visitor.RamlValidationService.preValidation(RamlValidationService.java:51)
at org.raml.parser.visitor.YamlValidationService.validate(YamlValidationService.java:64)
at org.raml.parser.visitor.YamlValidationService.validate(YamlValidationService.java:95)
at org.raml.parser.visitor.YamlValidationService.validate(YamlValidationService.java:77)

Being able to see positions and messages describing RAML nature of the error would be nice.

Initially the problem arose with RAML->JAX-RS generator. https://github.com/mulesoft/raml-for-jax-rs/issues/103 I post this issue as the generator makes use of the 0.9-SNAPSHOT parser.
