Version 2.2.0 - Kitakata

New features

1. Added a new configuration option validation.failUnrecognisedHeaders. This is the analogue to failUnrecognisedParams, but for samplesheet headers. The default is false which means that unrecognized headers throw a warning instead of an error.
2. Added a new configuration option validation.summary.hideParams. This option takes a list of parameter names to hide from the parameters summary created by paramsSummaryMap() and paramsSummaryLog()

Bug fixes

1. Fixed a bug in samplesheetToList that caused output mixing when the function was used more than once in channel operators.
2. Added a missing depencency for email format validation.
3. All path formats (with exception to file-path-pattern) will now give a proper error message when a file-path-pattern has been used.

Improvements

1. Improved the exists keyword documentation with a warning about an edge case.
2. Updated the error messages. Custom error messages provided in the JSON schema will now be appended to the original error messages instead of overwriting them.
