Import from GEDCOM

The GEDCOM file format is defined by the GEDCOM 5.5 Specfication, found
at http://www.familysearch.org/GEDCOM/GEDCOM55.EXE

The basic structure is a line with three attributes:

<LEVEL> <TOKEN> <DATA>

Because of this structure, it does not lend itself to more traditional
parsing techniques, such as LALR. The LEVEL token implies too much to be
useful in this context. While this makes parsing more difficult, it
does provide one very beneficial feature for GEDCOM: Error recoverability.
GEDCOM is a poorly implemented standard, primarily because it is a poor
standard to begin with. 

Most commercial applications that implement GEDCOM output add custom 
extensions, and feel free to violate the existing structure. If one were
cynical, one might believe that the commercial programs were trying to
make it difficult to transfer your data to another application.

This parser takes a different approach to parsing a GEDCOM file. The first
state, Lexer, reads lines from the file, and does some basic lexical
analysis on each line (actually several lines, since it automatically
combines CONT and CONC tagged lines). Each logical line returned to this
parser contains:

  Level, Token, Token text, Data, and line number.

The Data field is typically text, but in some cases, it may be a integer 
value representing an enumerated type or a GRAMPS object (in the case of
dates).

The parser works on the current level. Each context and level has a an 
associated table (dictionary) of functions indexed by the corresponding
TOKEN. When a token is found, we index into the table to find the function
associated with the token. If no token is found, a function that skips the
line and all subordinate (lines with a higher number). If a function is 
found, then we call that function, which in turn processes the line, and
all tokens at the lower level. 

For example:

1 BIRT
  2 DATE 1 JAN 2000
  2 UKNOWN TAG
    3 NOTE DATA

The function parsing the individual at level 1, would encounter the BIRT tag.
It would look up the BIRT token in the table to see if a function as defined 
for this TOKEN, and pass control to this function. This function would then
start parsing level 2. It would encounter the DATE tag, look up the 
corresponding function in the level 2 table, and pass control to its 
associated function. This function would terminate, and return control back to
the level 2 parser, which would then encounter the "UKNOWN" tag. Since this is
not a valid token, it would not be in the table, and a function that would skip
all lines until the next level 2 token is found (in this case, skipping the 
"3 NOTE DATA" line.
