Checks occurrences of the subsequences `subseq`

among the event sequences and returns the result according to the selected `method`

.

list of subsequences (an event subsequence object) such as created by |

`constraint` |
Time constraints overriding those used to compute |

`rules` |
If set to |

There are three methods implemented:
`"count"`

counts the number of occurrence of each given subsequence in each event sequence;
`"presence"`

returns 1 if the subsequence is present, 0 otherwise;
`"age"`

returns the age of appearance of each subsequence in each event sequence.
In case of multiple possibilities, the age of the first occurrence is returned. When the subsequence is not in the sequence, -1 is returned.

The return value is a matrix where each row corresponds to a sequence (row names are set accordingly) and each column corresponds to a subsequence (col names are set accordingly). The cells of the matrix contain the requested values (count, presence-absence indicator or age).
