refact(doc-processor): rename plugins to processors
feat(doc-processor): order processors by dependency
fix(doc-extractor): use config.basePath
fix(template-finder): use cwd for relative paths
fix(docGeneratorFactory): fileReaderFactory takes only config
fix(doc-renderer): get the outputPath from the config
fix(gen-docs): fix config and file paths
fix(angularjs package): templateFolder not templatePath
fix(paths processor): source file must be made relative

doc.file and doc.basePath are now absolute so we must compute the relative
path for the output.
fix(angularjs processors): path was renamed to paths
fix(paths processor spec): provide basePath for testing
fix(angularjs processors): set up dependencies
feat(examples processor): compute an id for the example
fix(doc-renderer): write outputPath on for debug
feat(examples processor): create docs from examples
