Default value for collectionFormat field is csv. Should be multi.

[pedrombl]

Currently the default value in the field collectionFormat is csv. However the default way of passing a list of parameters is multi (foo=bar&foo=baz). Talking with ron, who_ and jeremyw in #swagger/freenode this was identified as a bug.

Here is the part of the code that does that ->

swagger-core/modules/swagger-jaxrs/src/main/java/io/swagger/jaxrs/ParameterProcessor.java

Line 97 in 9c67549

p.collectionFormat("csv");

For the sake of documentation, the format is csv because of the intent in 1.3.X and we tried to keep it backwards compatible. However, since it really doesn't make sense and breaks the API documentation then it definitely needs to be multi. I believe this makes allowMultiple obsolete, but for now it should probably also give a multi value.

Fixed in develop_2.0.
