CollectionSpecParser (cdm-core 5.5.1 API)

java.lang.Object
- thredds.inventory.CollectionSpecParser

```
@ThreadSafe
public class CollectionSpecParser
extends Object
```
Parses the collection specification string.
the idea is that one copies the full path of an example dataset, then edits it

Example: "/data/ldm/pub/native/grid/NCEP/GFS/Alaska_191km/** /GFS_Alaska_191km_#yyyyMMdd_HHmm#\.grib1$"
- rootDir ="/data/ldm/pub/native/grid/NCEP/GFS/Alaska_191km"/
- subdirs=true (because ** is present)
- dateFormatMark="GFS_Alaska_191km_#yyyyMMdd_HHmm"
- regExp='GFS_Alaska_191km_.............\.grib1$
Example: "Q:/grid/grib/grib1/data/agg/.*\.grb"
- rootDir ="Q:/grid/grib/grib1/data/agg/"/
- subdirs=false
- dateFormatMark=null
- useName=yes
- regexp= ".*\.grb" (anything ending with .grb)
