Find neares match between a vector of observations and a vector of alternatives

1	find_near(observ_vector, match_vector, n_near = 5)

`observ_vector`	named vector or value to find a match from 'match_vector'. If the vector has no names function will still work, but the resulting 'period_1_id' variable will be empty.
`match_vector`	named vector which is used to find a nearest match to the 'observ_vector'.
`n_near`	number of the nearest observations to derive a random match. If 'n_near' is greater than 'length(match_vector)', minimum out of two is used to create a sample for selecting a random match value.

A dataframe with the number of rows equall to the lenght of the 'observ_vector' vector and one mathcing value and its index from the 'match_vector' corresponding to each value afrom the 'observ_vector'.
