Class Description

 The LogID class contains a log ID number (encoding of detector
 element position) as well as functions to obtain the location of
 log in question. LogID is used in the CalHit class.

 Default constructor
 All fields in tagword initialized to 0

 Create a LogID object with number tag

 Destructor

 Returns the log number

 Check if given value is a valid Column number:

 Check if given value is a valid pipe number:

 fill Layer, Column fields from ID fields:

 fill Pipeline, ADC Sequence, etc. from Geometry fields:

 Test the validity of a particular tag structure.
 Ensures that fields which don't use all possible values are
 within bounds.  Compares 'geometric' and 'electronic' position data
 and ensure that they are equivalent.

 In this function, we must ensure that the (Pipeline, Sequence, XY)
 and (Layer, Column) data map to identical logs.  If this is not the
 case, then the data encoded in the tagword is contradictory and
 should not be used.  This function also tests fields to ensure that
 values are within valid range.  It is important that this function
 is called on all tag words before they are stored or used!

 Returns the GLAST tower this log belongs to.  In the '99/2000
 beamtest, this value is always 0.

 Returns the column of the log in the calorimeter
 Columns are numberd 0-9.  Looking at the positive X face of the cal
 the log ends are numbered 0-9 from left to right.  Looking at the
 Positive Y face of the cal, the log ends are numbered 0-9 from right
 to left.

 Returns the layer this log is in.  Layers are numbered from
 0: (closest to TKR) to 7: (furthest from TKR).

 Returns the id of this log.  Each log in the calorimeter has a unique
 id value based upon it's position in the cal.

 Returns the electronics pipeline the log is read out through

 Returns the electronics ADC sequence the log is read out from

 Returns whether the log is in an x or y plane of the cal.

 Set value of tag word to tagVal if taVal is valid

 Fill tag word from values in a tag struct.

 return column value from tag word:

 Sets the column field in the tag word

 Returns the unique id of this log

 Sets the XY field in the tag word

 return layer value from tag word:

 return layer value from tag word:

 return ADC sequence value from tag word:

 Sets the layer field in the tag word
