A model to manage likelihood functions, environmental masks and behavioural
likelihood functions for pre-derived satellite locations. There are some options for configuration,
but this
may be considered a template for any given model. The model *function* exists
simply to make the object construction simple.

`day` |
vector of date-times for each light level |

`X` |
matrix of pre-derived satellite locations |

`proposal.x` |
function from object managing X proposals |

`proposal.z` |
function from object managing Z proposals |

`mask.x` |
lookup function for X's against masks |

`mask.z` |
lookup function for Z's against masks |

`fix.release` |
logical - is the release point known? |

`fix.recapture` |
logical - is the recapture point known? |

`start.x` |
starting positions for the primary locations, see |

`start.z` |
starting positions for the intermediat locations. |

`posn.sigma` |
variance for locations |

`behav.dist` |
distribution to use for behavioural constraint |

`behav.mean` |
mean to use for behavioural distribution |

`behav.sd` |
variance for behavioural distribution |

`proj.string` |
PROJ.4 string for coordinate system used |

`posn.sigma`

may be a single value for all estimates, or a vector of values for each position
estimate.

Transformation of coordinates is supported via a simple function that
only performs coordinate transforms if `proj.string`

is not
longlat. See `project`

for the underlying functionality.

See `solar.model`

for some related detail.

These are simple wrapper functions to create the desired model for use
in `metropolis`

. These models are structurally very simple
and may be easily edited as required.
