Matrix parameters don't work

[Nic2020]

Example:

module Example
    using ModelBaseEcon
    model = Model()
    @variables model x
    @shocks model e
    @parameters model begin
        c = [0.1 0.2]
    end
    @equations model begin
        x[t] = c[1,1] * x[t-1] + c[1,2] * x[t-2] + e[t]
    end
    @initialize model
end

Example.model.equations[:_EQ1].resid
# Shows c[1] everywhere: var"#x#0#" - (c[1] * var"#x#-1#" + (c[1] * var"#x#-2#" + var"#e#0#"))
# Instead of: var"#x#0#" - (c[1,1] * var"#x#-1#" + (c[1,2] * var"#x#-2#" + var"#e#0#"))

This was fixed in v0.6.3 under #67 (under model.jl line 1043):

name, index = ex.args was replaced by name, index... = ex.args
